Abstract: An absorbent pad (1) such as an incontinence pad comprises a liquid-impervious back sheet (3) with spaced islands (4) of absorbent material thereon. A liquid-pervious cover sheet (7) has pockets (5) formed therein, in which the islands (4) of absorbent material are disposed. The cover sheet is secured, either adhesively or by heat sealing, directly to the impervious sheet (3) along lines that separate the islands of absorbent material and the pockets that contain them. The pad is formed by applying a strip of cover sheet material to a rotating multi-perforate drum and forming the pockets in the cover sheet material either mechanically, or by drawing hot air inwardly through the holes in the drum in the case of a heat-deformable material such as polypropylene fibers. The drum then rotates past a pocket-filling station, where absorbent material such as cellulose fluff is drawn into the pockets by vacuum applied internally of the drum. The cover sheet is then applied to the composite of cover sheet and absorbent material, and is firmly bonded to lines of cover sheet material that are free from absorbent material between the pockets, overlying the bridges that separate the holes through the drum. The composite is then removed from the drum and cut to size.

Abstract: TRACTOR TRANSMISSION    ABSTRACT OF THE INVENTION          A drop box transmission is especially suited for use  in heavy  equipment  of  the  four-wheel  drive, bi-directional Type 1, that is capable of being driven in opposite directions with equal speed and power ranges. The transmission has a four shaft drop from an input shaft carrying high and low range gears alternatively driving a second shaft positioned below the input shaft. A series of gears mounted rotatably on the second shaft are in constant mesh with compatible gears on a third shaft below the second shaft.  The second shaft gears are selectively and alternatively engaged with the  second shaft to be driven by it.  Each of these gears is in con-stant mesh with a corresponding gear rotating with a third shaft below the  second shaft.   The third shaft drives a drive gear meshing with a forward drive gear on a fourth,  output shaft below the third shaft and also drives a gear on a reversing counter shaft carrying a second  gear  meshing  with  a  reverse  drive  gear  also carrier on the fourth shaft.   The forward and reverse drive gears are rotatable on the fourth shaft and are alternatively coupled to it to provide final drive to the fourth shaft.

Filed: 1990-03-14
Granted: 1994-10-18
Abstract: An apparatus comprising a Viterbi decoder which decodes received convolutional code data in accordance with the Viterbi algorithm and provides path metrics. Among the path metrics, a path metric comparator detects the maximum and minimum path metrics for each data symbol.  The path metric comparator selects the minimum difference among differences between the maximum and minimum path metrics.  An apparatus also comprises a field strength detector which detects the electromagnetic field strength of a radio signal containing the convolutional code data.  Upon the minimum path metric difference and the field strength, an interference detector checks if interference exists in the radio signal.  The minimum path metric difference may be used for an antenna diversity system.

Title: Partitioning optimizations in an optimizing compiler
Inventor: MARKSTEIN PETER W
IPC: G06F9/45
Filed: 1990-06-26
Granted: 1994-09-13
Abstract: A computer program is optimized prior to carrying out the final  compilation.   Subgraphs  within  the  program  are identified and examined for optimization beginning with the entire  program  as  the  largest  subgraph.  The  number  of entities  in  each  subgraph  which  are  relevant  to  each dimension of arrays used to represent data flow equations is determined. Next, the amount of memory required to contain the  arrays  is determined.  If that memory requirement is within a predefined memory usage limit for the compilation, then a specified procedure of the compilation process is applied.  If the memory requirement to contain the arrays exceeds  the  predefined  memory  usage   limit  for  the compilation,  the  process  is  repeated  for  successively smaller subgraphs within the program in an attempt to find a subgraph to which the memory limits allow application of the specified procedure.
